Abstract

The utility model provides a gear autorotation clamp driving suture device. The gear autorotation clamp driving suture device comprises a mounting shell, an arc suture needle, a guide frame, a rotation control piece and a clamping assembly. The rotating control piece and the clamping assembly are arranged in the direction of the rotating axis of the arc-shaped suture needle, and in the arrangement mode, in the radial direction of the circle where the arc-shaped suture hole is located, the rotating control piece and the clamping assembly are not overlapped with the suture groove, so that the rotating control piece and the clamping assembly are prevented from interfering with human mucosal tissue entering the suture groove; the suture groove can contain more human mucosa tissues, so that the arc-shaped suture needle can effectively suture the human mucosa tissues; besides, the clamping locking piece can be fixed at any position of the arc-shaped suture needle, so that the arc-shaped suture needle can be driven to rotate at any angle, and the precision requirement of matching between the clamping locking piece and the arc-shaped suture needle is greatly reduced; in this way, the situation that the device loses efficacy due to the fact that the matching precision between the clamping locking piece and the arc-shaped suture needle is not enough is avoided.

Description

Technical Field

[0001] The present application relates to the field of minimally invasive technology, and in particular to a gear-driven self-rotating clamp-driven suturing device. Background Art

[0002] In the existing technology of suturing human mucosal tissue defects / wounds under soft or rigid endoscopy, a semi-automatic suture technology using an arc-shaped suture needle can achieve mechanized needle threading, greatly improving the efficiency of the operation.

[0003] In the existing arc-shaped suture needle technology, most of them drive the arc-shaped suture needle to rotate by interfering with the fixed locking points on the surface of the arc-shaped suture needle. There is a problem with this method. Once the locking points are misplaced, the device will fail. At the same time, this requires a high degree of precision in the matching of the parts of the device, which will also increase the difficulty of manufacturing. In addition, this arc-shaped suture needle is similar to a C-type, and the mucosal tissue to be sutured must be located within the C-shaped mouth. If the C-shaped mouth is too small or blocked by other structures of the instrument, this will result in a small amount of sutured mucosal tissue or insufficient depth, thereby affecting the suturing effect.

The following discussion provides multiple embodiments of the present application.

Therefore, if one embodiment contains A, B, C, and another embodiment contains a combination of B and D, then the present application should also be considered to include an embodiment containing one or more of all other possible combinations of A, B, C, D, although the embodiment may not be clearly recorded in the following text. In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0049] like Figures 1 to 19 As shown, the gear self-rotating clamp driven suturing device 300 provided in the present application includes: a mounting shell 10 , an arc-shaped suturing needle 20 , a guide frame 30 , a rotation control member 40 and a clamping assembly 50 .

[0050] like Figures 1 to 4 As shown, the mounting shell 10 includes a shell 11 and a base 12. The base 12 is provided with a suture groove 13 and an arc-shaped suture hole 14. The suture groove 13 is configured to accommodate human mucosal tissue. The mounting shell 10 is provided with a mounting hole, which is configured to be assembled and connected with a matching piece. Specifically, as Figure 1 and Figure 19 As shown, the matching component is an endoscope 100 or an operating handle 200. The solution of using the gear-driven self-rotating clamp to drive the suturing device and the operating handle in combination is applied in the scenario of rigid endoscope minimally invasive surgery.

[0051] The arcuate suture needle 20 is rotatably disposed in the arcuate suture hole 14 .

[0052] like Figures 1 to 4 As shown, the guide frame 30 is fixed on the mounting shell 10 (specifically, the guide frame 30 is fixed on the base 12 and is located in the mounting shell 10), and a guide groove 31 is provided on the guide frame 30, and the guide groove 31 extends along the rotation direction of the arc-shaped suture needle 20. A first engaging tooth 33 is provided on one side wall of the guide groove 31, and a guide hole 32 is provided on the guide frame 30 on the rotation axis of the arc-shaped suture needle 20. The guide hole 32 extends along the rotation direction of the arc-shaped suture needle 20, and the guide hole 32 is connected to the guide groove 31.

[0053] The rotation control member 40 includes a control tube 41 and an annular second meshing tooth 42. In the rotation direction of the arc-shaped suture needle 20, the second meshing tooth 42 is arranged along the circumference of the control tube 41. The second meshing tooth 42 is located in the guide groove 31 and cooperates with the first meshing tooth 33. The second meshing tooth 42 is arranged at the other end of the control tube 41, and the other end of the control tube 41 extends out of the mounting shell 10.

[0054] like Figure 6 As shown, the clamping assembly 50 includes a clamping lock 51 and a clamping control 52. The clamping lock 51 is located on the base 12. A matching space 513 is provided on the clamping lock 51. The matching space 513 matches the arc-shaped suture needle 20. One end of the clamping control 52 passes through the control tube 41 and is connected to the clamping lock 51. The other end of the clamping control 52 extends out of the other end of the control tube 41. The clamping control 52 is configured to control the tightening of the matching space 513 of the clamping lock 51 so that the clamping lock 51 is fixedly connected to the arc-shaped suture needle 20.

[0055] The gear self-rotating clamp driven suturing device 300 provided by the present application, the rotation control member 40 and the clamping assembly 50 are arranged along the direction of the rotation axis of the arc-shaped suturing needle 20. The above-mentioned arrangement makes the rotation control member 40 and the clamping assembly 50 not overlap with the suturing groove 13 in the radial direction of the circle where the arc-shaped suturing hole 14 is located, thereby avoiding the interference of the rotation control member 40 and the clamping assembly 50 with the human mucosal tissue entering the suturing groove 13, so that the suturing groove 13 can accommodate more human mucosal tissue, thereby enabling the arc-shaped suturing needle 20 to effectively suturing the human mucosal tissue, thereby ensuring the suturing effect of the human mucosal tissue; in addition, the clamping locking member 5 The clamping lock 51 can be fixed at any position of the arc-shaped suture needle 20, thereby being able to drive the arc-shaped suture needle 20 to rotate at any angle. This greatly reduces the precision requirement for the fit between the clamping lock 51 and the arc-shaped suture needle 20, thereby avoiding the occurrence of device failure caused by insufficient fit between the clamping lock 51 and the arc-shaped suture needle 20. When the arc-shaped suture needle 20 is blocked from puncturing harder human mucosal tissue or the rotation stroke is insufficient, the clamping lock 51 can adjust the fixed position point in time to provide the arc-shaped suture needle 20 with sufficient puncture force and rotation stroke to achieve suturing of the human mucosal tissue, thereby improving the efficiency of the surgical operation.

[0056] like Figures 6 to 8 As shown, in a specific embodiment of the present application, the control tube 41 includes a driving section 411 and a control section 412 .

[0057] The second meshing teeth 42 are provided at one end of the driving section 411 and are located on the outer surface of the driving section 411 .

[0058] One end of the control section 412 is connected to the other end of the driving section 411 , and the other end of the control section 412 extends out of the mounting housing 10 .

[0059] The above structure makes the second meshing teeth 42 and the driving section 411 an integrated structure, thereby ensuring the connection strength between the second meshing teeth 42 and the driving section 411, avoiding the probability of the second meshing teeth 42 falling off the driving section 411, and improving the reliability of the product; on the other hand, the second meshing teeth 42 and the driving section 411 can be made using an integrated molding process, thereby reducing the parts assembly links and reducing the occurrence of parts loosening.

[0060] In a specific embodiment of the present application, the control tube includes a driving section and a control section.

[0061] The rotary control also includes a drive gear.

[0062] The driving gear has a second meshing tooth, the driving section is connected to the driving gear, and a through hole is provided on the driving gear, which is communicated with the driving section.

[0063] According to existing process technology, the driving gear and the driving section can be manufactured and assembled separately, which facilitates the manufacture of the device.

[0064] like Figures 9 to 14 As shown, in one embodiment of the present application, the gear self-rotating clamp driven suturing device 300 further includes: a guide member 60 .

[0065] The guide member 60 is disposed between the control tube 41 and the wall of the guide hole 32 . The guide member 60 is connected to the control tube 41 and the wall of the guide hole 32 , respectively. The guide member 60 can move relative to the guide frame 30 .

[0066] The setting of the guide member 60 eliminates the gap between the control tube 41 and the hole wall of the guide hole 32, avoids the shaking or deviation of the control tube 41 when moving in the guide hole 32, improves the accuracy and reliability of the movement, and thus avoids the situation where the control tube 41 controls the arc suture needle 20 to move sideways and get stuck in the arc suture hole 14, that is, ensures that the arc suture needle 20 moves smoothly in the arc suture hole 14 and does not get sideways and get stuck, so that the arc suture needle 20 can suture the mucosal tissue more smoothly.

[0067] like Figures 9 to 12 As shown, in one embodiment of the present application, the guide member 60 includes a second bearing 61 and a sliding member 62 .

[0068] The second bearing 61 is disposed in the guide hole 32 , and the control tube 41 is connected to the inner ring of the second bearing 61 .

[0069] The sliding member 62 is disposed between the outer ring of the second bearing 61 and the wall of the guide hole 32 . The sliding member 62 is connected to the outer ring of the second bearing 61 and the wall of the guide hole 32 , respectively.

[0070] The setting of the second bearing 61 ensures that the control tube 41 can rotate relative to the guide frame 30, and the setting of the sliding member 62 ensures that the control tube 41 can slide relative to the guide frame 30. The above structure is simple and can ensure that the arc-shaped suture needle 20 moves smoothly in the arc-shaped suture hole 14 without being tilted or stuck, so that the arc-shaped suture needle 20 can suture the mucosal tissue more smoothly.

[0071] like Figure 9 and Figure 10 As shown, in a specific embodiment of the present application, the sliding member 62 is a ball.

[0072] In the rotation direction of the arc-shaped suture needle 20 , a plurality of balls are provided on the hole wall of the guide hole 32 , and the balls can rotate relative to the guide frame 30 .

[0073] The ball makes the friction between the outer ring of the second bearing 61 and the wall of the guide hole 32 rolling friction, thereby reducing the friction between the outer ring of the second bearing 61 and the wall of the guide hole 32, that is, reducing the force required to drive the control tube 41 to move, and improving the comfort of product use; in addition, the ball makes the movement of the control tube 41 more stable and easier to control through the second bearing 61.

[0074] like Figure 11 and Figure 12 As shown, in another specific embodiment of the present application, a slide groove is provided on the hole wall of the guide hole 32 in the rotation direction of the arc-shaped suture needle 20, and the sliding member 62 is a guide rail, which is fixed on the outer ring of the second bearing 61 and extends into the slide groove, and the guide rail can slide in the slide groove.

[0075] The cooperation between the guide rail and the slide groove increases the contact area between the sliding member 62 and the guide frame 30, that is, the second bearing 61 plays a limiting role on the control tube 41, thereby more effectively avoiding the shaking or deviation of the control tube 41 when moving in the guide hole 32, improving the accuracy and reliability of the movement, and thus avoiding the situation where the control tube 41 controls the arc suture needle 20 to move sideways and get stuck in the arc suture hole 14, that is, ensuring that the arc suture needle 20 moves smoothly in the arc suture hole 14 and will not get sideways and get stuck, so that the arc suture needle 20 can suture the mucosal tissue more smoothly.

[0076] like Figure 13 and Figure 14 As shown, in a specific embodiment of the present application, the guide member 60 is a ball.

[0077] The ball can control the tube 41 to rotate relative to the guide frame 30, and can also ensure that the rotating control part 40 and the clamping assembly 50 slide relative to the guide frame 30. The ball setting eliminates the gap between the control tube 41 and the hole wall of the guide hole 32, avoids shaking or deviation of the control tube 41 when moving in the guide hole 32, improves the accuracy and reliability of the movement, and thus avoids the arc suture needle 20 controlled by the control tube 41 from being stuck sideways in the arc suture hole 14, that is, ensures that the arc suture needle 20 moves smoothly in the arc suture hole 14 and will not be stuck sideways, so that the arc suture needle 20 can suture the mucosal tissue more smoothly.

[0078] Several embodiments of the clamping and locking member 51 are described in detail below with reference to the accompanying drawings.

[0079] Example 1

[0080] like Figures 6 to 8 As shown, the clamping and locking member 51 includes a first clamping arm 511 and a second clamping arm 512. In a specific embodiment of the present application, a reset member 514 is provided between the first clamping arm 511 and the second clamping arm 512; the reset member 514 ensures that the states of the first clamping arm 511 and the second clamping arm 512 can be accurately returned to the initial state, thereby improving the reliability and stability of the system and preventing the clamping and locking member 51 from being unable to reset and thus being unable to repeatedly clamp the curved suture needle 20, thereby ensuring the suturing effect on human mucosal tissue.

[0081] A matching space 513 is provided between the first clamping arm 511 and the second clamping arm 512 . The clamping control member 52 is configured to control the relative movement of the first clamping arm 511 and the second clamping arm 512 to tighten the matching space 513 to clamp the arc-shaped suture needle 20 .

[0082] The operator controls the first clamping arm 511 and the second clamping arm 512 through the clamping control member 52 to tighten the matching space 513 between the first clamping arm 511 and the second clamping arm 512 to clamp the arcuate suture needle 20. Then, the operator rotates the second meshing tooth 42 by operating the rotation control member 40. Since the second meshing tooth 42 is meshed with the first meshing tooth 33 on the side wall of the guide groove 31, the second meshing tooth 42 will move along the circumference of the guide groove 31, so that the rotation control member 40 drives the clamping assembly 50 to move in the first direction to drive the arcuate suture needle 20 to puncture and suture the human mucosal tissue; when the second meshing tooth 42 moves to the end position, the operator controls the first clamping arm 511 and the second clamping arm 512 through the clamping control member 52 to relax the matching space 513, so that the first clamping arm 511 and the second clamping arm 512 are aligned with the arcuate suture needle 20. The closing needle 20 is separated, and the operator controls the second meshing tooth 42 to rotate in the opposite direction by rotating the control part 40, so that the rotation control part 40 drives the clamping assembly 50 to move in a second direction opposite to the first direction, so that the second meshing tooth 42 returns to the initial position, and repeats the above operation at least once, so that the arc-shaped suture needle 20 rotates one circle relative to the base 12, so that the arc-shaped suture needle 20 passes through the human mucosal tissue, and so on, so that the arc-shaped suture needle 20 rotates one circle relative to the shell 11 multiple times to complete the suturing of the human mucosal tissue. In the above process, since the clamping locking part 51 can be fixed at any position of the arc-shaped suture needle 20, the clamping locking part 51 can rotate the arc-shaped suture needle 20 to any angle, and the clamping locking part 51 drives the arc-shaped suture needle 20 to rotate at least twice to realize the arc-shaped suture needle 20 rotating 360° along its rotation axis.

[0083] The clamping and locking member 51 has a simple and compact structural design, does not involve complicated tiny precision parts, and has fewer designed structures, thereby simplifying the structure of the entire system.

[0084] like Figure 8 As shown, in one embodiment of the present application, a mounting groove 4113 is provided at one end of the driving section 411 .

[0085] The clamping control component 52 includes a first bearing 521 and a control cable 522. The first bearing 521 is fixed in the mounting groove 4113. The control cable 522 is connected to the clamping locking component 51. The control cable 522 is configured to control the clamping locking component 51 to be engaged with the inner ring of the first bearing 521 so as to tighten the fitting space 513 between the first clamping arm 511 and the second clamping arm 512.

[0086] The control rope 522 can drive one end of the first clamping arm 511 and the second clamping arm 512 to be clamped in the first bearing 521, and the first bearing 521 can ensure that the first clamping arm 511 and the second clamping arm 512 rotate relative to the guide frame 30. After one end of the first clamping arm 511 and the second clamping arm 512 are clamped in the first bearing 521, the holding force between the first clamping arm 511 and the second clamping arm 512 is increased, thereby effectively ensuring the effective clamping of the arc needle by the clamping locking component 51, so that the arc suture needle 20 can effectively sew the human mucosal tissue, thereby ensuring the suturing effect on the human mucosal tissue.

[0087] like Figure 8 As shown, in one embodiment of the present application, the driving section 411 includes a receiving portion 4111 and a control portion 4112 , and the mounting groove 4113 is provided on the receiving portion 4111 .

[0088] The guide frame 30 includes a first frame body 34 and a second frame body 35 , and the guide hole 32 passes through the first frame body 34 and the second frame body 35 .

[0089] A guide groove 31 is provided on the first frame 34 .

[0090] The second frame 35 is disposed between the first frame 34 and the base 12 . A matching groove is provided on the second frame 35 , and the receiving portion 4111 is disposed in the matching groove.

[0091] The first frame 34 and the second frame 35 effectively limit the driving section 411, avoiding shaking or deviation of the driving section 411 when moving in the guide hole 32, improving the accuracy and reliability of the movement, and thus avoiding the arc suture needle 20 controlled by the driving section 411 from being stuck sideways in the arc suture hole 14, that is, ensuring that the arc suture needle 20 moves smoothly in the arc suture hole 14 and will not be stuck sideways, so that the arc suture needle 20 can suture the mucosal tissue more smoothly.

[0092] Example 2

[0093] like Figure 15 As shown, the clamping and locking member 51 is a fixed ring 515.

[0094] The fixing ring 515 forms a matching space 513 , and the fixing ring 515 is sleeved on the arc-shaped suture needle 20 .

[0095] The clamping control member 52 controls the fixing ring 515 to become smaller and tighten the matching space 513 so that the clamping locking member 51 is fixedly connected to the arc-shaped suture needle 20 .

[0096] The operator controls the fixed ring 515 to become smaller through the clamping control member 52, that is, the fitting space 513 surrounded by the fixed ring 515 is tightened, so that the fixed ring 515 clamps the arcuate suture needle 20. Then, the operator operates the rotary control member 40 to rotate the second meshing teeth 42. Since the second meshing teeth 42 are engaged with the first meshing teeth 33 on the side wall of the guide groove 31, the second meshing teeth 42 will move along the circumference of the guide groove 31, so that the rotary control member 40 drives the clamping assembly 50 to move along the first direction, thereby driving the arcuate suture needle 20 to move and suture the human mucosal tissue. When the second meshing tooth 42 moves to the end position, the operator controls the fixed ring 515 to become larger through the clamping control member 52, even if the matching space 513 surrounded by the fixed ring 515 is relaxed, so that the fixed ring 515 is separated from the arc-shaped suture needle 20. The operator controls the second meshing tooth 42 to rotate in the opposite direction by the rotating control member 40, so that the rotating control member 40 drives the clamping assembly 50 to move in a second direction opposite to the first direction, so that the second meshing tooth 42 returns to the initial position. Repeat the above operation at least once, so that the arc-shaped suture needle 20 is 0 rotates one circle relative to the base 12 to allow the arc-shaped suture needle 20 to pass through the human mucosal tissue. By analogy, the arc-shaped suture needle 20 rotates one circle relative to the housing 11 multiple times to complete the suturing of the human mucosal tissue. In the above process, since the clamping and locking member 51 can be fixed at any position of the arc-shaped suture needle 20, the clamping and locking member 51 can rotate the arc-shaped suture needle 20 to any angle. The clamping and locking member 51 drives the arc-shaped suture needle 20 to rotate at least twice to achieve a 360° rotation of the arc-shaped suture needle 20 along its rotation axis.

[0097] Several embodiments of the base 12 are described in detail below with reference to the accompanying drawings.

[0098] Example 1

[0099] like Figures 1 to 5 As shown, the base 12 includes a base plate 121 and a cover plate 122 .

[0100] A first arc-shaped groove 123 is provided on the base plate 121 .

[0101] The cover plate 122 is provided with a second arc-shaped groove 124 . The cover plate 122 is covered on the base plate 121 . The second arc-shaped groove 124 and the first arc-shaped groove 123 form an arc-shaped suture hole 14 .

[0102] The opening 141 of the arc-shaped suture hole 14 is disposed on the cover plate 122 . In the radial direction of the circle where the arc-shaped suture hole 14 is located, the width of the second arc-shaped groove 124 is smaller than the width of the first arc-shaped groove 123 .

[0103] The above structure enables the opening 141 of the arcuate suture hole 14 to face the mating component, so that the suture 70 connected to the arcuate suture needle 20 passes through the mating component (for example, the working channel of the flexible and rigid endoscopes 100), thereby facilitating the operator to perform endoscopic surgery to meet the operational requirements of some specific minimally invasive surgeries.

[0104] In one embodiment of the present application, the wall surface of the cover plate 122 located at the suture groove 13 is an inclined surface 131 .

[0105] The setting of the inclined surface 131 increases the accommodation space of the suture groove 13, so that the suture groove 13 can accommodate more human mucosal tissue and makes it easier for the suture 70 to be removed from the opening 141, thereby avoiding the suture being retained in the arc-shaped suture hole 14 and interfering with the rotation of the arc-shaped suture needle 20.

[0106] Example 2

[0107] like Figures 16 to 18 As shown, the base 12 includes a base plate 121 and a cover plate 122 .

[0108] A first arc-shaped groove 123 is provided on the base plate 121 .

[0109] The cover plate 122 is provided with a second arc-shaped groove 124 . The cover plate 122 is covered on the base plate 121 . The second arc-shaped groove 124 and the first arc-shaped groove 123 form an arc-shaped suture hole 14 .

[0110] A slot plate 125 is provided on the cover plate 122. In the direction of the rotation axis of the arc-shaped suture needle 20, the slot plate 125 extends away from the cover plate 122. The slot wall of the second arc-shaped slot 124 is connected to one side of the slot plate 125. The slot plate 125 and the slot wall of the suture slot 13 form an opening 141 of the arc-shaped suture hole 14.

[0111] The opening 141 formed by the groove plate 125 and the groove wall of the suture groove 13 is opened, and its edge is shallow from the depth of the arc-shaped needle hole and faces the human mucosal tissue, so that when the arc-shaped suture needle 20 rotates in the arc-shaped needle hole, the suture 70 connected to the arc-shaped suture needle 20 can smoothly escape from the arc-shaped needle hole, thereby reducing the probability of the suture 70 being entangled in the arc-shaped needle hole, and ensuring that the suture device can sew the human mucosal tissue smoothly.

On this basis, various replacements and improvements can be made to the present application, all of which fall within the scope of protection of the present application.
